Ransomware Threatens Africa's Critical Infrastructure: A 2026 Assessment

Executive Summary

As of March 2026, ransomware attacks have escalated across Africa, with cybercriminal groups intensifying efforts to compromise critical infrastructure sectors, including power grids, water systems, industrial control systems (ICS), healthcare, and the financial sector. This briefing provides an analysis of the current threat landscape, highlighting notable threat actors, their tactics, and the implications for national security and economic stability.

Current Threat Landscape

Ransomware has emerged as a predominant cyber threat in Africa, with over half of INTERPOL's African member countries reporting attacks against their critical infrastructure. Between January and December 2023, nearly half of the African countries surveyed experienced ransomware attacks targeting government infrastructure, hospitals, financial institutions, and internet service providers.

Implications and Recommendations

The escalating frequency and sophistication of ransomware attacks on critical infrastructure in Africa pose significant risks to national security and economic stability. To mitigate these threats, the following measures are recommended:

• Enhanced Cybersecurity Measures: Organizations should implement robust cybersecurity protocols, including regular system updates, employee training on phishing attacks, and comprehensive incident response plans.

• International Collaboration: Strengthening cooperation among African nations and international partners is crucial for sharing threat intelligence and coordinating responses to cyber threats.

• Public Awareness Campaigns: Raising awareness about the risks of ransomware and promoting best practices among the public and private sectors can help reduce the attack surface.

By adopting a proactive and collaborative approach, African nations can bolster their defenses against ransomware attacks, safeguarding critical infrastructure and ensuring the continuity of essential services.
